Ciba has acquired ColorViz SAS, a
French start-up company with which it has cooperated since 2005. With
know-how in CAD software development and material application, ColorViz
has developed unique technology solutions for 3-D visualization of colors
in substrates such as plastic and paint. Its software facilitates communication
between industrial designers and specifiers and their material suppliers,
making the product development process more efficient. The acquisition
further differentiates Ciba's color management service offer and
affords it access to a wider range of customers. Through Color Services,
Ciba offers innovative solutions combining software systems and consulting
to help customers enhance their productivity in communicating and producing
colors.

Sonia Megert Marshall, Global Head of Color Services at Ciba, explains: "We confirmed the formidable potential of ColorViz's
technology while acting as exclusive worldwide distributor for its software.
That's when we also realized that the synergies between our color
formulation technology and ColorViz's visualization technology could
be fully exploited only in a closer collaboration. Now we can accelerate
the development of highly innovative tools for color design and specification."

Christophe Dauga, Managing Director of ColorViz SAS, adds: "Ciba' and ColorViz's advanced technologies will
be merged into one unique and strong offering. We will be expanding the
possibilities to reproduce colors accurately and to the highest quality.
Our aim is to take digital color communication way beyond its current
boundaries."

Mr. Dauga will remain head of ColorViz while also taking a leading role
in Ciba' Color Services organization. ColorViz
will continue to be based in Aix-en-Provence, France.
